MINERS LAMP.

Specification of Letters Patent.

Application filed December 2, 1908.

Patented Sept. 14, 1909.

Serial No. 465,645.

To aZZ whom it concern:

Be it known that I, ADLETIA MAE VAN Lrnw, a citizen of the UnitedStates, and a resident of Houghton, in the county of Houghton and Stateof Michigan, have invented a new and Improved Miners Lamp, of which thefollowing is a full, clear, and exact description.

This invention relates to miners lamps for burning oil, wax and thelike, and more particularly to a lamp of this class comprising a body, awick tube projecting through the spout of the body, and a memberremovably mounted upon the wick tube and arranged longitudinally thereofto assist in conducting heat from the flame to the illuminant within thebody, and having a part extending over the projecting end of the wicktube. The member is hollow, so that it conducts air to the flame toassist the combustion.

The object of the invention is to provide a simple, inexpensive andlight weight miners lamp, which is compact in form, which is adapted toburn wax or the like as an illuminant, in which the combustion of thewax or other substance is complete, and which thus obviates theproduction of smoke and other noxious gases.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings formin a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is alongitudinal section of an embodiment of my invention; Fig. 2 is a planview of the wick tube; Fig. 3 is a perspective view of the memberremovably mounted upon the wick tube; Fig. 4 is a transverse section onthe line H of Fig. 1; and Fig. 5 is a perspective view showing a part ofthe lamp body, a part of the spout, the projecting wick tube, and themember mounted thereon.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that while the same is particularly usefulas a means for employing wax and the like for producing a light, anyother illuminant such as oil or petroleum can be equally well employed.If wax is used, it is necessary to provide means for transmitting heatfrom the flame to the main body of the wax, in order to liquefy orsoften the same, to enable the wick to draw the wax to the point ofcombustion by capillary action. In my lamp, a member is mounted upon thewick tube and extends longitudinally of the same; it is fashioned frommetal or other heat-conducting material for the above purpose. Themember is hollow, and has wings or other parts extending over theprojecting end of the wick tube and serves as an air conduit forsupplying the flame with sufficient air to insure complete combustion,thereby obviating the production of smoke, carbon and noxious gases.This feature is of great importance, especially if the lamp is to beused in poorly ventilated mines where such gases are often a source 'ofdanger to the workers in the same.

Referring more particularly to the drawings, I prefer to provide thelamp with a cylindrical or slightly tapered body 10, fashioned fromsheet metal and having a hinged lid or cover 1 of any suitable form. Thebody has a hook or hanger 12 by means of which the lamp can be removablyattached to the cap or some part of the clothing of the user.Preferably, at the side remote from the hanger, the body has a taperedspout 13, communicating interiorly with the lamp body through a suitableopening 1 1, in the wall of the lamp. The shape of the body permitsshaved wax or the like to be easily introduced into the same. I haveshown in the type of lamp illustrated herewith, for example, a liquidilluminant 15 such as oil or the like. The spout 13 has an opening 16,through which projects an inclined wick tube 17, which extends into thebody and has its lower end near the bottom of the same. Preferably, thewick tube is flat, to receive a correspondingly shaped wick 18, which Ihave found to be'particularly advantageous in connection with a lamp forburning wax. The wick has the lower end shredded to provide a completecontact with the illun1inant. Furthermore, near the lower end, the wicktube has an opening 19 through which the illuminant can enter the wicktube. At the projecting end, near the spout, the wick tube has cut awayportions 20 forming outwardly disposed spaced flanges 21 A member 22,preferably of Usection, has at the opposite sides near one end,outwardly extending lugs 23, adapted to be slidably positioned under theflanges 21, to hold the member removably in place. The latter hasshoulders 24:, adapted to engage at the end of the wick tube to limitthe movement .of the member when it is being inserted in positionbetween the flanges 21. Owing to the U-form of the member, itconstitutes an air tube or conduit so that air can pass from a pointremote from the flame to the flame. Furthermore, the member has wings 25ex tending over the end of the wick tube and slightly spaced therefrom,so that these wings are located in the flame when the lamp is lighted.The member thus becomes heated and serves to transmit heat along thewick tube toward the illuminant within the body.

It will be understood that the member 22 may be of any suitable form,and that the wings 25 may be replaced by other parts adapted to projectinto the flame, or for a like purpose. Near its outer end, the wick tubehas openings 26, for the purpose of admitting the air to the wick toassist in the combustion and to allow the wick to be adj usted. The mmber 22 serves a like purpose as has been explained above, and thus the.flame is provided with sufficient air to insure substantially completecombustion, thereby minimizing the production of smoke, soot or thelike.

Having thus described my invention 1 claim as new, and desire to secureby Letters Patent:

1. A miners lamp, comprising a body, a wick tube projecting from saidbody and having a flange, and a heat conducting member mounted upon saidtube and having a part extending over the end thereof into the flame,said member constituting an air conduit, and having a lug removablyengaging said flange.

2. A miners lamp, comprising a body, a wick tube projecting from saidbody, and an air conducting member mounted upon said tube and arrangedto feed air into the flame teams of said tube from said flame towardsaid body, and having a part disposed transversely across the end ofsaid tube.

4. A miners lamp, comprising a body, a spout, a wick tube projectingfrom said spout, and a member removably mounted upon said tube andhaving a passage therethrough, said member further having a wingextending transversely over the end of said tube.

5. A miners lamp, comprising a body, a spout, a wick tube extending fromsaid body through said spout and projecting from the latter, said tubehaving oifset flanges, and a hollow member having lugs adapted removablyto engage under said flanges and having a shoulder adapted to engage atthe end of said tube, said member having a wing extending over the endof said tube into the flame.

6. In a miners lamp adapted to burn wax, a flat wick tube adapted toreceive a flat wick, said tube having openings near the ends thereof,and a member removably mounted upon said tube and having a Wingprojecting over the end thereof, said memher being hollow to serve as anair conduit,

and being fashioned from a heat-conducting material. 7

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
